* sh-tdep.c (sh_pseudo_register_read): New function. Renamed and modified version of obsolete sh_fetch_pseudo_register. (sh_fetch_pseudo_register): Rename to sh_pseudo_register_read. (sh4_register_read): New function. (sh_pseudo_register_write): New function. Renamed and modified version of obsolete sh_store_pseudo_register. (sh_store_pseudo_register): Rename to sh_pseudo_register_write. (sh4_register_write): New function. (sh_gdbarch_init): Remove setting of gdbarch function fetch_pseudo_register and store_pseudo_register. Remove setting of register_convert_to_raw, register_convert_to_virtual, register_convertible. (sh_sh4_register_convertible): Delete. No longer needed. All is taken care by architecture specific functions register_read/register_write. (sh_sh4_register_convert_to_virtual): Make static. (sh_sh4_register_convert_to_raw): Ditto.
